Bitcoin for sure lacks a privacy layer even if part of the most well-known Core developers have previously looked into this issue many years ago.  Bitcoin users nowadays seem too scared of a government blockage to adopt a privacy layer, trading privacy for short term profit.  My gut feeling says we should either get privacy straight inside Bitcoin's Core functions or we do not at all.  And my gut feeling also says that we will likely never get a privacy layer as a consequence of Bitcoin users fears.  Solutions such as the one proposed by Wasabi or Joinmarket are fine, but they are temporary solutions only.

I saw a lot of users on Bitcoin Talk reply that Wasabi's Coin Joins and Chip Mixer are proper solutions someone can hang on to but I strongly disagree.  Without default privacy, it is easy to separate non private from private users and discriminate them by considering private users money launderers or terrorist funders.

Deposit your mixed coins on a Centralized Exchange and you will be asked for documents.  Deposit Monero instead and they will probably not.  I am saying this according to my personal experience and it is bad.  You can not put the equal sign between two Bitcoins anymore, which is very concerning.
